The specific embodiment
In conjunction with the accompanying drawings the present invention is described in further detail below by the specific embodiment.
Device for analyzing samples is by sampling, detects, and obtains the data of sample composition with this.Sampling needle needs to clean after gathering sample in the process of using, and needs to use the sampling needle cleaning device to clean.
Please refer to Fig. 1 to Fig. 2, waterfall type sampling needle cleaning device comprises sampling needle 1 and service sink 3, and sampling needle 1 has inwall cleaning fluid liquid outlet, and the cleaning fluid of this inwall cleaning fluid liquid outlet outgoing is used to clean the sampling needle inwall; Service sink 3 is used to provide the cleaning position, have on the sidewall that cleans groove and described cleaning groove and have an outer wall cleaning fluid liquid outlet at least, the cleaning fluid of this outer wall cleaning fluid liquid outlet outgoing is used to clean the sampling needle outer wall, drain the discharge orifice of this inwall cleaning fluid and this outer wall cleaning fluid on this service sink 3 in addition, wherein, sampling needle moves to the cleaning position; Open the inwall cleaning fluid, clean the sampling needle inwall; Open the outer wall cleaning fluid, clean the sampling needle outer wall; Sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from least to sampling needle cleans liquid level; The sampling needle translation goes out the cleaning position.Because service sink 3 adopts the groove structure, sampling needle need not move vertically to the cleaning position and clean, and has saved the testing time of device for analyzing samples, has improved the testing efficiency of device for analyzing samples; Since sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from least to sampling needle cleans liquid level, has improved the measuring accuracy of device for analyzing samples.
On the basis of above-mentioned embodiment, sampling needle adopts hollow structure, hollow structure partly forms sampling needle inwall cleaning fluid liquid outlet channel, on the needle point of sampling needle to inwall cleaning fluid liquid outlet 2 should be arranged, service sink 3 is used to provide the cleaning position, the service sink 3 upwards middle part of a side is provided with the cleaning groove that an opening makes progress, this cleaning groove is a sunk groove that forms on service sink, behind the sampling needle application of sample directly horizontal movement carry out the cleaning of sampling needle in the rinse bath, do not need the motion of vertical direction, save time, improved the test speed of device for analyzing samples.The first outer wall cleaning fluid liquid outlet 4a and the second outer wall cleaning fluid liquid outlet 4b are arranged on the sidewall of rinse bath, the bottom of rinse bath is provided with three cascading water passages, on rinse bath respectively to three cascading water holes should be arranged, sampling needle 1 is over against the first discharge orifice 5a of service sink 3, the inwall cleaning fluid that is used for earial drainage sampling needle 1, the both sides of rinse bath also are respectively equipped with the second discharge orifice 5b and the 3rd discharge orifice 5c, the outer wall cleaning fluid that is used for earial drainage sampling needle 1, certainly, when middle cascading water orifice flow amount is little, sampling needle 1 outer wall cleaning fluid also can both pass through the second discharge orifice 5b and the 3rd discharge orifice 5c earial drainage, also can carry out cascading water by the first cascading water hole 5a, equally, the inwall cleaning fluid also can both pass through the first discharge orifice 5a earial drainage, also can pass through the second earial drainage 5b and the 3rd discharge orifice 5c earial drainage.
The outer wall cleaning fluid is ejected on the outer wall of sampling needle 1 by the first outer wall cleaning fluid liquid outlet 4a and second outer wall cleaning liquid outlet 4b of service sink 3, surround its sampling needle needle point outer wall and carry out the outer wall cleaning, this moment, the distance of sampling needle needle point and service sink 3 bottoms was H, the height that sampling needle 1 needle point outer wall cleaning fluid covers is H1, and needle point outer wall cleaning fluid cover height H1 is meant the distance of peak on the sampling needle that can be ejected into from the sampling needle needle point to the outer wall cleaning fluid.Outer wall cleaning fluid liquid outlet can have one, also two or more can be arranged; The fluid injection direction of outer wall cleaning fluid can horizontal-jet, also can make progress or sprays to declivity; The shape of outer wall cleaning fluid liquid outlet can be circular hole, mounting hole, also can be square opening etc.Inwall cleaning fluid liquid outlet has only one usually, and the shape of inwall cleaning fluid liquid outlet is normally circular.
Because rinse bath is groove, so sampling needle 1 opens wide on the horizontal movement course bearing, so sampling needle 1 can directly clean after horizontally rotating the cleaning position, need not to do vertical descending motion, saved the testing time of device for analyzing samples.Wherein, sampling needle moves to the cleaning position; Open the inwall cleaning fluid, clean the sampling needle inwall; Open the outer wall cleaning fluid, clean the sampling needle outer wall; Sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from least to sampling needle cleans liquid level, because sampling needle and/or service sink move in the opposite direction, this motion breaks away from the cleaning fluid liquid level at least to sampling needle, make sampling needle slowly break away from the cleaning liquid level, reduce extension liquid, improved the measuring accuracy of device for analyzing samples.It both can be that service sink maintains static that sampling needle and/or service sink move in the opposite direction, and sampling needle moves upward; Can also be that sampling needle maintains static, service sink moves downward; Can certainly be that sampling needle moves upward, service sink moves downward simultaneously, as long as allow sampling needle slowly break away from cleaning fluid, just can reduce extension liquid, improves the measuring accuracy of device for analyzing samples.
Because sampling needle 1 horizontal movement course bearing opens wide, no solid wall surface stops, if sampling needle and/or service sink not to mutually away from the direction motion break away from liquid level at least to sampling needle, then when the first outer wall cleaning fluid liquid outlet 4a and second outer wall cleaned liquid outlet 4b and close, cleaning fluid was rapidly from the first cascading water hole 5a, the second cascading water hole 5b and the 3rd cascading water hole 5c cascading water.Because the surface tension coefficient of 1 pair of cleaning fluid of sampling needle is obviously greater than the surface tension coefficient of air to water, so cleaning fluid is suspended on sampling needle 1 needle point outer wall surface under the effect of surperficial absorption affinity, and it is more to cause sampling needle 1 to hang liquid measure.Finish back needle point extension liquid if sampling needle 1 cleans, when next inhaling sample/reagent, the drop of suspension incorporates sample/reagent it is diluted, and particularly the sample application amount is less, and dilution phenomenon shows more seriously, causes test result inaccurate; Each in addition test is cleaned and is finished the back to hang liquid measure different, has certain randomness, thereby to the dilute strength difference of sample/reagent, causes the repeated variation of test result.In a word, the extension liquid of sampling needle 1 needle point can influence instrument test result's accuracy and repeatability, thereby influences measuring accuracy.So present embodiment adopt sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from least to sampling needle cleans liquid level, makes sampling needle slowly break away from cleaning fluid, has reduced extension liquid, has improved the measuring accuracy of device for analyzing samples.
A kind of sampling needle cleaning method of the present invention, comprising: sampling needle moves to the cleaning position; Open the inwall cleaning fluid, clean the sampling needle inwall; Open the outer wall cleaning fluid, clean the sampling needle outer wall; Sampling needle and/or service sink to mutually away from the direction motion, this motion breaks away from least to sampling needle cleans liquid level, the sampling needle translation goes out the cleaning position.
Please refer to as Fig. 3, in one embodiment, sampling needle moves to the cleaning position, opens the inwall cleaning fluid, cleans the sampling needle inwall; Open the outer wall cleaning fluid, clean the sampling needle outer wall; Sampling needle 1 and/or service sink 3 to mutually away from the direction motion, this motion breaks away from least to sampling needle 1 cleans liquid level, sampling needle 1 translation goes out the cleaning position.Break away from the cleaning liquid level because sampling needle and/or service sink move in the opposite direction at least to sampling needle, make sampling needle slowly break away from the cleaning liquid level, improved the measuring accuracy of device for analyzing samples.
On the basis of above-mentioned embodiment, the mode that sampling needle moves to the cleaning position had both comprised rectilinear translation, also comprised curvilinear translation; Open the inwall cleaning fluid, the liquid that the inwall cleaning fluid penetrates by inwall cleaning fluid liquid outlet carries out inwall and cleans; Open the outer wall cleaning fluid, the liquid that the outer wall cleaning fluid penetrates by outer wall cleaning fluid liquid outlet carries out outer wall and cleans; Sampling needle and/or service sink to mutually away from the method for direction motion, both comprised that service sink maintained static, sampling needle moves upward, and comprises that also sampling needle maintains static, service sink moves downward, and comprises that also sampling needle moves upward, service sink moves downward simultaneously.When sampling needle carries out inwall, outer wall cleaning, can carry out at once sampling needle and/or service sink to mutually away from the step of direction motion, also can after sampling needle, outer wall clean a period of time, carry out again sampling needle and/or service sink to mutually away from the step of direction motion.The inwall cleaning fluid and the outer wall cleaning fluid of sampling needle both can be opened simultaneously, also can successively open, and both can open the inwall cleaning fluid earlier, cleaned the sampling needle inwall earlier, also can open the outer wall cleaning fluid earlier, cleaned the sampling needle outer wall earlier.After sampling needle moves to the cleaning position, can open inwall cleaning fluid and/or outer wall cleaning fluid at once, open inwall cleaning fluid and/or outer wall cleaning fluid again after also can waiting a period of time.Break away from the cleaning liquid level because sampling needle and/or service sink move in the opposite direction at least to sampling needle, make sampling needle slowly break away from the cleaning liquid level, improved the measuring accuracy of device for analyzing samples.
In embodiment more specifically, sampling needle and/or service sink to mutually away from the direction motion be meant with service sink and maintain static, sampling needle moves upward, it highly is H1 that the needle point outer wall cleans, when cleaning is near completion, cleaning fluid continues sampling needle 1 is carried out outer wall when cleaning, sampling needle 1 with certain speed from position 1b vertical lifting to position 1c, moving both vertically highly is H2; Last sampling needle 1 carries out suction sample/reagent action from position 1c horizontal movement to position 1d.Break away from the cleaning liquid level because sampling needle moves upward up to sampling needle, the speed of reasonable disposition sampling needle 1 vertical ascending motion can be reduced to bottom line with outer wall hanging liquid measure simultaneously; Make cleaning fluid slowly separate with sampling needle 1, because the intermolecular active force of cleaning fluid is obviously greater than the surface tension of 1 pair of cleaning fluid of sampling needle, cleaning fluid leaves sampling needle 1 outer wall surface under the effect of molecular force, hangs liquid measure thereby reduce the sampling needle needle point.
On the basis of above-mentioned embodiment, also comprise the step of closing the outer wall cleaning fluid: when sampling needle is transported to its height greater than H1, close sampling needle outer wall cleaning fluid.Above-mentioned steps makes sampling needle break away from the outer wall cleaning fluid naturally, makes sampling needle slowly break away from the outer wall cleaning fluid, has reduced extension liquid, has improved the precision of pattern detection.After sampling needle breaks away from the outer wall cleaning fluid, can close the outer wall cleaning fluid.After sampling needle breaks away from the outer wall cleaning fluid, more early close the outer wall cleaning fluid and save cleaning fluid more.
On the basis of above-mentioned embodiment, also comprise the step of closing the inwall cleaning fluid, before the sampling needle translation goes out the cleaning position, also comprise the step of closing the inwall cleaning fluid.The inwall cleaning fluid is more early closed and is saved cleaning fluid more, and the outer wall cleaning fluid opening time washes clean more in the Changqing more.Can take all factors into consideration above-mentioned factor and determine the shut-in time of inwall cleaning fluid.
In the above-described embodiment, the distance H of sampling needle needle point and service sink bottom is as long as satisfy the requirement that can carry out horizontal movement, and positioning accuracy request was low when sampling needle 1 was cleaned.
On the basis of above-mentioned embodiment, please refer to Fig. 4, the outer wall of sampling needle 1 cleans, inwall cleans, move both vertically and the sequential relationship of horizontal movement, is defined as follows time parameter:
T1---sampling needle 1 cleans when being near completion, and sampling needle 1 begins to do vertical ascending motion, moves to just to break away from the time of cleaning liquid level (vertical range of sampling needle 1 motion is H1);
T2---sampling needle 1 just break away from clean liquid level to the time that sampling needle 1 is finished ascending motion (vertical range that sampling needle 1 moves is H2) be T2;
The total time that T---sampling needle 1 moves both vertically, T=T1+T2;
T3---sampling needle 1 is finished the time of vertical ascending motion to the beginning horizontal movement;
T4---close the outer wall cleaning fluid is finished vertical ascending motion to sampling needle 1 time;
T5---close the time of inwall cleaning fluid to sampling needle 1 beginning horizontal movement;
Each time is satisfied following relation:
After T2＞0, sampling needle 1 rise to and break away from the cleaning liquid level, in preferred embodiment, sampling needle continues to rise and maintains a certain distance until cleaning liquid level with outer wall, reduce the outer wall cleaning and close back needle point extension liquid, for reducing needle point extension liquid, T2 tries one's best little of to save time simultaneously.
T3 〉=0, ability horizontal movement after sampling needle 1 moves both vertically and finishes, T3 tries one's best little of to save time.
0≤T4≤T2, the outer wall cleaning fluid be closed in sampling needle 1 break away from clean liquid level after, sampling needle 1 is finished before the vertical ascending motion, sampling needle 1 breaks away from and cleans the outer wall that cleaning fluid behind the liquid level can not clean to sampling needle 1, therefore can close the outer wall cleaning fluid immediately, to save cleaning fluid.
0≤T5≤T+T3, inwall cleaning fluid are closed in sampling needle 1 to begin after the rising, before sampling needle 1 horizontal movement.The time of inwall cleaning fluid is long more, and that then cleans is clean more, and simultaneously, the time of cleaning is short more, saves cleaning fluid more.
The outer wall cleaning fluid must be closed before the sampling needle horizontal movement after sampling needle breaks away from the cleaning liquid level; The inwall cleaning fluid is after the sampling needle ascending motion, and any moment before the sampling needle horizontal movement can close.
As mistake! Do not find Reference source.Be depicted as preferred embodiment a kind ofly, work as T3=0, T4=T2 during T5=0, closes the outer wall cleaning fluid at once when sampling needle breaks away from outer wall cleaning fluid liquid level, and outer wall cleans water saving; Just close the inwall cleaning fluid in sampling needle moves both vertically process before the sampling needle horizontal movement, the inwall scavenging period is the longest; After sampling needle moves both vertically, carry out horizontal movement immediately, save time.When saving sampling needle 1 cleaning, in the rise and fall time, solve sampling needle 1 outer wall hanging liquid problem, improve the measuring accuracy of instrument; Service sink 3 is simple in structure, and is low to the cleaning requirement precision.The first cascading water hole 5a diameter can reduce and spatter the liquid phenomenon when occurring cleaning more greatly; Through actual test, this cleaning way can better solve sampling needle 1 and clean the liquid problem of hanging, perusal does not have obvious drop and is suspended on sampling needle 1 needle point outer wall, and it is also quite little that quantitative test is hung liquid measure, and device for analyzing samples precision of test result and repeatability are also better.
In another embodiment, sampling needle and/or service sink to mutually away from the direction motion be meant that sampling needle maintains static, service sink moves downward.Sampling needle cleans when being near completion, and when the cleaning fluid continuation was carried out the outer wall cleaning to sampling needle 1, sampling needle 1 was motionless, and service sink is done vertical descending motion with certain speed under the drive of motor, breaks away from fully until sampling needle 1 and cleans liquid level; Make sampling needle also slowly break away from and clean liquid level, can reduce the sampling needle needle point equally and hang liquid.In a word, as long as make sampling needle slowly break away from cleaning fluid, can reach and reduce the effect that the sampling needle needle point is hung liquid.
The present invention also provides a kind of device for analyzing samples, comprises above-mentioned sampling needle cleaning device.
Above content be in conjunction with concrete embodiment to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
